Transitional image for a display screen on the top of a portable computer



FIG. 1 is a front view of the first image in the sequence for a transitional image for a display screen on the top of a portable computer showing my new design;

FIG. 2 is a front view of the second image thereof;

FIG. 3 is a front view of the third image thereof;

FIG. 4 is a front view of the fourth image thereof; and,

FIG. 5 is a front view of the fifth image thereof.

The appearance of the transitional image sequentially transitions between the images shown in FIGS. 1–5. The process or period in which one image transitions to another forms no part of the claimed design. The broken line showings of the elements inside the transitional image, the display screen, and the top of a portable computer are for illustrative purposes only and form no part of the claimed design. 

The ornamental design for a transitional image for a display screen on the top of a portable computer, as shown and described.
